.fi

.SH DESCRIPTION
.sp
.LP
The \fBdlpi_enabmulti()\fR function enables reception of messages destined to
the multicast address pointed to by \fIaddrp\fR on the \fBDLPI\fR link instance
associated with \fBDLPI\fR handle \fIdh\fR. The \fBDLPI\fR link instance will
pass up only those messages destined for enabled multicast addresses. This
operation can be performed in any \fBDLPI\fR state of a handle.
.sp
.LP
The \fBdlpi_disabmulti()\fR function disables a specified multicast address
pointed to by \fIaddrp\fR on the \fBDLPI\fR link instance associated with
\fBDLPI\fR handle \fIdh\fR. This operation can be performed in any \fBDLPI\fR
state of a handle.
.SH RETURN VALUES
.sp
.LP
Upon success, \fBDLPI_SUCCESS\fR is returned. If \fBDL_SYSERR\fR is returned,
\fBerrno\fR contains the specific UNIX system error value. Otherwise, a
\fBDLPI\fR error value defined in \fB<sys/dlpi.h>\fR or \fBDLPI_EINHANDLE\fR is
returned.
